https://bugzilla.redhat.com/show_bug.cgi?id=1173507 It occurred to me that OpenStack uses the following XML when not using regular huge pages: <memoryBacking> <hugepages> <page size='4' unit='KiB'/> </hugepages> </memoryBacking> However, since we are expecting to see huge pages only, we fail to startup the domain with following error: libvirtError: internal error: Unable to find any usable hugetlbfs mount for 4 KiB While regular system pages are not huge pages technically, our code is prepared for that and if it helps OpenStack (or other management applications) we should cope with that.
